Keep call-site arguments separate from the input configuration instead of merging them into a full configuration copy. Resolve configuration values as instantiation traverses them, preserving parent context until values are copied, resolved, and detached for target calls. This avoids copying and resolving unrelated configuration, supports runtime objects that OmegaConf cannot store, and permits state established by earlier targets to affect later arguments. Preserve structured runtime conversion behavior, callable targets, recursive overrides, tuple and list conversion, partial instantiation, and serialization safety. Remove the Optuna-only deepcopy bypass. Document the interpolation and Structured Config compatibility changes. Closes #3216
